THE PUZZLOR

Choose your crew

Successfully navigating the waters during sea voyages is a challenging task. A captain’s most important decision is selecting the right crew for the voyage. A mix of different skill sets is required to sail the ship efficiently, navigate to the destination and fish for good along the way.

Table 1 shows a list of crew members available for you to hire for the voyage. Each crew member demands a salary for the voyage and has different skill levels of fishing, sailing and navigation.

In order for your journey to be successful, you must have a cumulative skill of 15 or more in each of the three skill categories from all of your chosen crew members. You may choose as many crew members as you like.
